Ok, here's my 'racing on a shoestring' budget....

Entries £1480 approx. (all rounds except for the last cadwell)
5 test days £475
Bike fuel £150
Fuel for the discovery £500
B & B at 4 rounds £240
2 sets of tyres £320
Trailer hire £300
Repairs £30 ( some glass fibre and a couple of cans of paint)
A few oil changes £60 appx.

So, around £3555 plus licence, membership costs etc.

I did have an engine rebuild and general going over of the bike by baines at the start of the year though... that cost £1300.
